To ZZ whom it may concern:

Be it known that l, FRANK A. Monroe, a citizen. of the United States., residing :it the city of .liunestowinv in'- the county of .Cheu- New York, have inund useful Improve- Clenning Oil-Wells, of

which the following, teken in connection with the accompanying drawings, is n specivented certain new ments in Devices for lo icntion. v

The invention relutes to improvements in the means for removing puruliin, the thickened product of petroleum, or other deletef rions substances `from the oil bearing portion of :in oil well; und the object of theimprovement is to provide a. surennd continuous means of uttaining fr high eliciency' of steam production so us to render the notion of the device more sure und continuous in operetion; und the invention consists in the novel features und combinations hereinafter set forth und claimed.

In the drawings, Figure 1 is en elevation of the oil well clen1ier,'certuin portions being broken :twny,' showing: the contormutionot' the outer casing: und the exits for the steam.

Like characters of reference refer to correspon din g ports in .the several views.`

'il he numeral 1.0 designates the eylindricztl or tubular' casing within which the different sections of the cleaner are assembled. The easing l() 'hns the top plete 12 therein for turning the plete 11 into the easing' 10 und supporting` the cleaner, and. the bottom platte 13 with the loop 1st therein for turning seid platte 13 into the casing 10, both the top :nul bottom plates beine preternbly threaded und screwed into the eusing' 10.

l/lrithin the und bottom plete 13 supported one upon the strong* volume oi steam ousin' its pressure :is possible und fory `ns long 'it time :is possible. 'lhe sections consist of :in oxygen. or other comprensed gus cylinder 15 to feed. the combustion, u heutingr secu sleztm producing section 17 on its u pper end, :t waiter tank section 18 casing 10 betgween top plete 11 u, number of sections are other to produce :t which is us continu- ,hole25 extending up through the seine .into the upper end 11 with the loop supported on said steam and heating section 16 und 17, and :1t the top e compressed air chamber 19.

`The five' sections 15, 16, 17, 18 and 19 are connected to one :mother :is follows: The top ot the cylinder' section lo is providedwith e bend 20 with n needle valve 21 in the top'of the head 20 to open and close the outlet 22. A cup 23 is screwed onto the heed 20 over the vnlvecontrolled upper end o seid head, which' cap 23 has an upward projection which is screwed into the bottom plate 24 of the .heating section 16. The cap 23 has e and has outlets 2G in -diierent directions nearr the top of the projection within the lheet pro-lv ducing section 1G.

An asbestos plutc'27 is provided within the heut producing'chamber section 16 over the upper end ot the oep 23 to protect the someto some extent from the heat producin fuel .after ignition'. Gerben block, charcos or other heetingffuel may be used within the heating chamber section 16. The ignition und steady burnin'of the .heat producing fuel is controlled and aided by the ges in the cylinder 15 as it escapes' in thedesired quantity through 'their/ents. 2 3e and 26 into seid section 1G around cup shaped heed -an lunion 28 is screwed 'the heating section 16 which has 'cone Shaped central upwardly meier-,ting portion 22? whichzstends down to The cup slumped heed 28 is screwed into the upper end of the cylinder- Aor 4tube which terms. the section 1G, und e secondl cylindrienl section 17 is screwed onto the upper end thereof for :i steam. production` chamber. 'lhewuter drips upon the cone-shaped upwardly extending' central part 29 thereby forming steunt, und the holes 30 which eX tend from the cup-shaped receptacle 28 out through the cylinder and into the outer easing 10 permit the excess of writer to drip down over the outer which being heated also vproducessteam. The upper end ot' the section 17 is closed by menus et' the screw plete 31 which has the opening; 32 therethrough directly over the cone 2S).

yiso' 'smaller than said casing projections 34 on the plate 31, the bottom piate 33 of the section 18 being screwed into the tube for said section. A small tube 35 is screwed through the center of plate 33 to permit the water to drip down therethrough onto the cone 29. The upper end of the tank 18 is closed by a plate 36 which has the small tube 37 inserted through the bottom plate 38 of the compressed air section 19, tube 37 being sufficiently small to aid' in controlling the tloiv of water. The tube 37 has a needle valve 39 in the upper end thereof with the stein 4() extending down through the upper plate 41 of the section 19. A valve 42 is provided in the upper plate 41 for'charging the compressed air section or cylinder 19.

In assembling the parts ready for operating the device the gas tank 15 and heating section 1G are attached to one another and charged with gas and charcoal or carbon blocks. Section 18 is illedwith Water .and section 19 charged with compressed air and the two connected to one another. It is then' apparent that the sections 15 and 16 may be inserted in the casing 10 resting firmly in thebottom of thesame but being sutliciently to permit the steam to pass down along the sides of the sections 16 17. The tank section 18 and section 19 having been charged with water and air are set upon the sections 15 and 16 and 17, aftelwhich the upper plug or head 11 is inserted.

The charcoal or combustible material in section 1G is ignited before the insertion of the section and a limited ow of gas is turned on by means of the valve 21 which permits the gas to flow up around the asbestos pad 27, thereby insuring a continuous combustion in the Chamber 11') and heating the Walls of said chamber and ythe cup-shaped plate 2S with its cone 29 for a' comparatively long period of time.

The sections 18 and 19 having been charged with water and gas are inserted with the tube extending down through the hole and the plate 33 resting upon the projections 34 thereby supporting the two upper sections within the casing 10. The needle valve n suflicient to permit a steady dripping of the water from the tank section 18 down through the pipe or tube 35 onto the conc 29, which being heated produces a steady column of steam, the sides of the cupshaped head 28 also assisting in this production l.of steam, the steam rises through the opt-'ning 32 and passes out through the ring ot holes 43 in the casing 10 against the walls of that portion of the oil well whichy it is desired to heat. Other rings of holes or openings for the stcani may be provided as at 4:1, the rings of openings lil and 4,4 being spaced apart as desired.

Any number of such rings of: holes may, i
